I had major issues with audio and subtitle sync. It was delayed by anywhere from 2 to 4 seconds. Had to revert back to version 2.5.3 which worked flawlessly. This had a different problem. A number of H/X264 rips with compressed headers would appear as simply green screen. I then switched to Handbrake which had its own problems with sharpness. Finally I worked out a flowchart for getting the exactly what I wanted as a final result.
What I need in my final result was 2000 kbps XVid Mpeg4 ASP, 720p resolution, sufficiently loud AC3 5.1 audio and SRT subtitles. This would make the final file of decent size 2000 to 2200 mb, compatible with all standalone players and playable on Atom powered netbooks also.
First of all I reverted to version 2.5.3. If the audio was DTS I would convert to AC3 using freeware SPG Audio Converter selecting AC3 and "Very High" as the format and quality setting. Inspect the file with MediaInfo to check if it had header stripping audio or video heders. If is was such then remux using mkvmerge 4.4 with the header compression set to off. Extract the subtitles. Rip the newly created mkv file through Avidemux 2.5.3 with my required settings + msharpen filter at default settings and external AC3 (512 kbps created by SPG audio converter) file as the audio source. Depending on the volume level of the AC3 file I would select DRC and gain between 3 and 5. Select mkv as the container and save. I always say NO to the H/X264 message that pops up when avidemux scans the input file.
I then run the resulting file through mkvmerge, add the previously extracted srt subtitles file and necessary comments to the track and global options. Then I am done.
Till today I was not aware that the compressed header was the problem for the green screen. Now that I know it has solved all my problems. It is slow but then I run 2 instances of avidemux simultaneously - my PC can handle it. CPU utilization does not exceed 70%.
I am from photographic field where every hair and pore on the face counts. The final result is a whole lot more than good enough. Handbrake does not come even close in quality!
Finally I have just downloaded the version 2.5.5 and will try it out tonight. I hope the sync problem from 2.5.4 has been taken care of. |
