Converted files are un-playable

Post by kdpap » Wed Nov 20, 2019 2:47 am

Description of problem or question:
I am new to using decoding programs, so hopefully the following describes the problem that I am having accurately.

I used the program to convert 2 downloaded .mp4 videos to .mp4 files playable from a thumb drive on a portable USB/DVD player. After figuring out which preset settings were compatible, it worked great for the 2 videos.

But after trying this for more videos a week later, all videos are unplayable on the USB player and even on Windows Media player. The Windows media player gives the message: "Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file."

I do not understand the change which is causing the program not to work anymore. Any help with this would be greatly appreciated.

Steps to reproduce the problem (If Applicable):
Below, I included the Activity Log for a trial which results in an unplayable file. This trial was stopped after 2 minutes of running.
After this, I included a Log for the original conversion of the same file that resulted in a playable file.

HandBrake version (e.g., 1.0.0):
HandBrake V1.2.2 (2019022300)



Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Windows 7 Home Premium Service Pack 1.

HandBrake Activity Log ***required*** (see How-to get an activity log)

Here is the Log for the last unplayable trial run. I stopped it after 2 minutes.

Re: Converted files are un-playable

Doesn't appear to be anything wrong with the file.

DVD players are notorious for having horrible support for media files. (The old Windows media player out the box isn't much better)
If I were to guess, it could be related to the fact your using Anamorphic, the output bitrate could be too high, it might take issue with variable framerate.

Re: Converted files are un-playable

s55 thank you for the reply.

The thing I do not understand is that the same source video worked fine the first time after extensive trial and error with the preset settings. I believe that I am using the same preset for the conversion for the new runs which don't work. The only difference is that for the new runs, I saved the preset as a custom one so that I do not have to enter all of the parameters each time.

During my initial troubleshoot, I started with the built-in preset "Fast 480p30", which began working on the player once I set the Audio Codec to MP3. I then increased the quality of the video to a maximum of "1 QP". I did notice that the audio codec kept switching back to "AAC" and I think it was set to "MP3" during the successful runs. I later found instructions on how to set the default audio codec in the "Selection Behavior" window to keep it from reverting back to "AAC".

When I compared the 2 logs, I noticed that there is a difference in the ""ID": 11" section. The unplayable run had "width": "854" but the run that worked had "width": "720". I am confused why there would be a difference if the same preset was used on the same source file (original source is 854 x 480). Also there are other differences in the logs such as: "PAR" section each have different values for "Num" and "Den" Could there be a setting in the new preset that is causing the problem?

Also both logs seem to show identical errors, so do you think these can be ruled out as the problem?

Thank you again

You want AAC audio passthrough. Mp3 is not universally recognized, and was / is not the reason your encodes began working. That's a misattribution.

If you will but take a logical troubleshooting approach:
  • Change only one thing at a time, then test
    Write it down
    Change it back before doing anything else
    Trust the defaults, not your imagination.
You will figure out your errors on your own.
If you make random changes expecting to pull a rabbit out of a hat, be careful what you wish for.

One of the biggest problems with most of the DVD/Bluray-Player and SmartTVs are the settings of video compression.
If you want high quality mp4 video files handbrake often use a higher Level of h264/h265 e.g. 5 and most of the TVs and other players only support Level 4.1.

It is the setting in the video tab near the profile. Although most of the players support aac audio and no other exotic format (opus, e-ac3, DTS, etc.).

The Level is not a quality metric, no such forward relationship exists. It is but an indicator of file architecture -- bitrate, resolution, and frame rate -- that comes after the fact, and not as a determinant.
The thing I do not understand is that the same source video worked fine the first time after extensive trial and error with the preset settings. I believe that I am using the same preset for the conversion for the new runs which don't work.
OP should click a normal preset, press Start, report succes or failure after allowing completion, and post the logs. OP feels some need to swim upstream by making arbitrary changes based on "belief," or "trial and error."

For example, and there are others, forcing QP of 1 on a hardware codec seems to negate my notion of "playability," and sensibility (643 Kbps source) Why? (Isn't QP 18 considered as visually lossless?) To another observer, it's vanilla SD.

Add to that the untracked changes made between the two encodes, one can expect a clear invitation to start over and suppress the urge to fix something.

All thanks for the help.


This weekend, I tried again with the same starting file from the logs above but this time changing only one parameter at a time and writing every parameter change down as I went along as musicvid suggested above. For all of the below, I did not convert the whole file, I performed only 3min runs to save time. I eventually got the file playing again on the portable usb player. Here is the sequence of parameter changes:

I started with the built in preset Fast 480p30 : This gave message on the usb player: video codec not supported
I changed video codec from H.264 to MPEG-4: usb player did not give any message, but still did not play
I changed Audio codec from AAC to MP3: usb player played file!

I then tried to make the quality better using the constant quality QP slider. When the above file played, it appeared blocky even on the small screen, so I decreased the QP factor from 20 to 15. (I am comparing the quality to the original file that was created in the above original log. When this file plays, it does not appear blocky and equivalent in sharpness to the original file on Windows media player). The resulting video still appeared blocky. After many trials, I found 5 QP to result in video which is equivalent to the original. I am confused, because from what I read, a value of 20 QP should be more than enough to match standard DVD quality.

Finally, I noticed a few things about the saved preset settings in the program that resulted in my original custom preset not working.
When I reopen the program and load my saved preset, I notice that the following settings are different even though I am positive that I saved them in the preset:

Dimensions/Width was at 854 even though the preset was saved with a value of 720. This changes the PAR values from 482x405 to 3856x3854. For some reason, the width keeps defaulting back to the source size of 854.

Audio/Codec was at AAC even though the preset was saved as MP3. I set the audio codec to MP3 in the selection behavior/Audio defaults/codec screen when i created the custom preset. For some reason it does not seem to save this and the codec keeps switching back to AAC.

Thanks again for any help.

RF is not the same as QP. QP 4-8 is probably a sane range for the old MPEG-4 codec.

Understood. And it is codec-specific. h264 works quite well at QP18, and that is the apparent decoder listed in the first log, not oldschool mpeg-4.

If the OP would care to upload a clean source sample (not YouTube), there are others here who can run quantitative tests to back their trials, maybe come up with a more universally playable solution.

That said, I'm very skeptical about the net effect of any Q-based encoder on a machine-coded source video at <1Mbps. Only a talking head against a static background could hope to survive that harsh treatment, whether or not it plays well.

The original poster is to be acknowledged for at least trying, if a bit indirectly. I'll be glad to help if I can, probably not until after the holiday weekend.

All

I performed many trial and error tests this holiday weekend and what I finally found is that the Handbrake settings were not the issue...it was the USB thumb drive!!

I am using a PNY 128GB USB 3.0 drive which is supposed to be backwards compatible to USB 2.0 per the package. My Windows 7 computer has a USB 2.0 port so everything should have worked fine. I even purchased a second identical USB 3.0 drive to see if the first one was defective. I had the same problem except that I could not even get any files to play from this drive.

When I repeated the test with an older USB 2.0 thumb drive, the video files played fine on both Windows media Player and the portable USB/DVD player!!

The incompatibility caused many weird results which led me to think it was the different settings for Handbrake that I was using. This included video files on the USB 3.0 drive working perfectly for only the first 2 videos that I converted a few weeks ago, but not for the rest. What clued me into this problem was that jpg picture files would not even work. But all this time text files were perfectly usable with Windows Notepad on both USB 3.0 drives.

Anyway, all thanks for the help
