Re: Quicktime to WMV

I would look into Adobe Premiere: http://www.adobe.com/products/premiere.html . It is a professional video editing software that will accept any video format. Stay away from Windows Movie Maker. It doesn't even let you specify the output resolution. The highest preset resolution is 640x480. Horrible...

Re: Macbook Pro overheating

Regardless of whether someone has a hardware problem or not, the developers should port over the Windows option of lowering process priority? I can barely watch a 480p h264 main profile video on Mac while I'm transcoding. It plays back at half the framerate. Mac : 2.2 GHz Core i7 - can't multitask W...

Re: How are b-adapt and b-frames related?

I'm hitting 100 FPS average on my turbo first pass with b-adapt=2, b-frames=4. When I do b-adapt=2, b-frames=5, I only top out around 70 fps. Seems like it makes a huge difference. Hope it doesn't hurt the PSNR too much.

Re: How are b-adapt and b-frames related?

Thanks for the suggestions.

With b-adapt=1 or b-adapt=2, will there ever be a case where higher b-frames could lower quality? Or can high b-frames only lower quality when b-adapt=0 because that's hardcoding the number of b-frames?

How are b-adapt and b-frames related?

This x264 article says b-frames should be 16 when b-adapt=1. b-adapt Default: 1 Set the adaptive B-frame placement decision algorithm. This setting controls how x264 decides between placing a P- or B-frame. 0. Disabled. Pick B-frames always. This is the same as what the older no-b-adapt setting did....

Macbook Pro overheating

I've been a long time user of Handbrake on Windows and have recently moved on to experimenting on Macbook Pro.

No way to set 59.94 FPS

I have a video that Handbrake detects as 59.94 FPS and VLC detects as ~119.88 FPS. From this cross-examination, it appears that this video is variable framerate. I'm dealing with a legacy player that can't handle variable framerate, so I would like to specify a hard framerate in Handbrake. I couldn'...

Re: List of new x264 options added to 0.9.5

You are right. VFR was the problem. It seems like most videos are in VFR because I havn't gotten a single one of my transcodes to play smoothly in old VLC with the "same as source' setting.

Re: List of new x264 options added to 0.9.5

Turning off Pyramidal B frames while transcoding in VLC 1.1.5 fixed the flickery problem when played back in old VLC. (Note that there is no hyphen in the parameter name) #transcode{vb=750, venc=x264{ weightp=0, bpyramid=none [/color] }, vcodec=h264, acodec=mp3, ab=96, channels=2, threads=2}:duplica...

List of new x264 options added to 0.9.5

Can someone please tell me the list of new x264 options added to 0.9.5 which are not backwards compatible with older h264 decoders? For one, I noticed that weighted P frames were turned on by default causing some old media players (namely VLC 0.8.6) to play videos almost 90% gray. So I turned them o...

Re: how to specify which section of video to transcode?

Rodeo, You are correct. I no longer have the nightly build, but I did a quick test on VLC 1.1.4 transcoding: #transcode{vb=750,height=480,venc=x264{weightp=0},vcodec=h264,acodec=mp3,ab=96,channels=2,threads=2}:duplicate{dst=standard{access=http,mux=asf,dst=localhost:1234}} The video plays fine in VL...

Re: how to specify which section of video to transcode?

I would gladly completely switch over to the nightly build to fix this doubling issue, but it fails to generate playable files for older media players. Is the nightly build using a different muxing or advanced x264 options that old media players can't understand? The videos it generates play fine in...

Re: double file lengths

I asked this last year. The answer was that certain audio sample rates cause this doubling effect to happen. No one answered on how to fix the problem, except to upgrade to the newest nightly build. I wish somehow there was a setting on 0.9.4 to fix this because the nightly generates files that olde...

Beginner's guide to capping the maximum bitrate?

I'm streaming videos online and need to keep under my maximum upload speed of 2 Mbps. Anytime I go over 2 Mbps, the video freezes for a while. Here's one of my typical transcodes (1000 kbps video + 96 kbps audio): ### CLI Query: -i "F:\uno.mkv" -t 1 -c 1 -o "F:\dos.mp4" -f mp4 -w 1024 -l 576 -e x264...

Re: how to specify which section of video to transcode?

I confirmed that the nightly build 0.9.4.3293 does not double the length of my weird files. It worked great.

I didn't see where to specify which section of the video I wanted to transcode. Where was this feature added to the nightly build?

Re: How to make handbrake run faster on XP?

Your single core Pentium 4 is not made for video processing. Video processing takes advantage of multiple cores. Here are my observations on downsampling the same 720p video on my two machines:

Intel Wolfdale E8400 - dual Core @ 3.0 GHz => 14 FPS
Intel Core i7 920 - quad core @ 2.66 GHz => 40 FPS

Re: how to specify which section of video to transcode?

Where is this "nightly build"? I went through all sections of the main site and could not find it. Is there an installer for it because I don't know anything about compiling.

how to specify which section of video to transcode?

I'm having trouble with videos coming from one website. The output file is always double in length of the input. The output file will play as expected for the first half in VLC media player. Then the second half will have no video, but has the audio track repeated. Is there anyway to tell Handbrake ...
