FRAME RATE / convert var to constant changes the length of the clip PLEASE HELP
FRAME RATE / convert var to constant changes the length of the clip PLEASE HELP
Windows 10 Enterprise LTSB 64 Bit
I have a video piano concert that was recorded with variable frame rate of 30fps.
I am using Adobe Premiere Pro and was advised by adobe to try converting this video file with handbrake.
I followed the instructions and set constant bitrate 29.97 fps and loosless quality rf=0.
The file I received was indeed constant 29.97, same quality but the whole clip was a little bit shorter.
I need the clip to be the same exact length what the original because it has to be perfectly sync to the audio.
Are there any other settings that i have to change ???
for example
Anamorphic / Modulus from the Picture tab
"Optimise Video" settings for Encoder Preset, Level, Tune, Profile on the Video tab
or maybe there are plenty of options / settings on Advance Tab once you enable it.
I am completly lost.
Thank you everyone for helping me out

Thanks for helping me out
I tried 2nd time
I changed to placebo (5 min clip in 4 hours), set encoder to high /film and turned off filters
The file is shorter than the original
Thanks

Try the nightly build with the a/v sync option.
Re: FRAME RATE / convert var to constant changes the length of the clip PLEASE HELP
How much is it out by?
That should be with audio sync corrected so you shouldn't have a sync problem.[14:54:24] vfr: 9000 frames output, 11 dropped and 0 duped for CFR/PFR

Looks like the audio is not being handled by HB, maybe being muxed in after?
Re: FRAME RATE / convert var to constant changes the length of the clip PLEASE HELP

Re: FRAME RATE / convert var to constant changes the length of the clip PLEASE HELP
How are you determining duration?
According to the log, your original is *not* 5:00.08. It is 5:00.28.
Also according to the log, 9000 frames were output. At 29.97fps framerate, the duration is 5:00.30.
The difference between 5.00.28 and 5.00.30 is less than 1 frame duration which is exactly what I would expect.

Re: FRAME RATE / convert var to constant changes the length of the clip PLEASE HELP
yes you are right log shows 5:00:28
when i open the converted file in adobe premiere pro it shows 4;59;28 ; original 5:00:08
this is i think 11 frames (
this is were i get the numbers from
correct me maybe i am wrong
1 sec is 30 frames
in the log it says 11 frames dropped (my guess is 11 frames = approximately 1/3rd of a second ???)
can you tell me what is the best way to check the length (exact duration) duration ?
if it is less than one frame i can accept it
When i open both files in handbrake and check duration in activity log i see:
original 5:00:28
converted 5:00:32
are those duration numbers 28/32 frames or or 1/100 of sec
thx

Re: FRAME RATE / convert var to constant changes the length of the clip PLEASE HELP
Your wrong. You selected 29.97 fps output framerate. So 1 second is 29.97 frames in your output file.correct me maybe i am wrong
1 sec is 30 frames
Your source was 300.28 seconds and 9011 frames.in the log it says 11 frames dropped
The number of frames when converting to 29.97fps will be 300.28 * 29.97 = 8999.39.
I.e. There will be about 11 fewer frames in a 300.28 second video at 29.97fps than in a 300.28 second video at 30fps.
Yup, those are the correct durationsWhen i open both files in handbrake and check duration in activity log i see:
original 5:00:28
converted 5:00:32
I don't understand the questionare those duration numbers 28/32 frames or or 1/100 of sec
