Avidemux Forum

I have been using MPEG4 ASP (ff) encoder.

Why? Unless you need compatibility to some extremely old hardware, you should use a modern codec like H.264 or HEVC (the latter does have compatibility issues with equipment which is not top-notch).

DivX is obsolete and massively inferior, resulting in much bigger file sizes if the source video was compressed with H.264.

I have been doing some simple editing and cropping on some mp4 files. I notice that the resulting saved file is larger than the original, even though I've removed some content from the original.

To get access to some of the filters, it appears you must change the video output choice. I have been using MPEG4 ASP (ff) encoder. Where am I going wrong? Other than the files growing size the program is working fine. I am using 2.7.1.

Thanks a lot.

ubuntu HWE 16.04.4 LTS 64 bit x86 SMP, QT5, x265 version 1.9: avidemux 2.7.1 180712-64bit HWE Xenial with x265 version 1.9

In avidemux 2.5  be a cool possibility. Change FPS to any  with no recoding.!  it fantastic option but unfortunately it removed in 2.6
Please RETURN THIS OPTION

Never heard of this option, but anyway, I don't think this is feasible with the current design of Avidemux and with modern video codecs.

If you want to speed up video by doubling fps, save audio as PCM, then apply the "Change FPS" video filter with the destination fps twice as high as the source one and re-encode the video. Load the audio into a wave editor, e.g. Audacity, and speed up it accordingly, save it as 16 bit low-endian .wav file. Load the reencoded video in Avidemux, add the .wav file as external audio and save it with video in copy mode and audio compressed with the codec of your liking.

Thank you, actually you have already pinpointed the issue:

[Ts Demuxer] Pes Packet too big

The PES packet payload size limit TS_PES_MAX_LIMIT, currently at https://github.com/mean00/avidemux2/blob/master/avidemux_plugins/ADM_demuxers/MpegTS/dmxTSPacket.cpp#L26, set to 2 MiB 9 years ago, is not sufficient for this stream. It would be great if you could provide a small (~300 MiB) sample, cut in binary way (like with the dd tool on Linux), from somewhere near the middle of the original TS file.
