[FFmpeg-user] Timecode based filenames
Question on Timecode Based Filenames: What is required to generate a filename based on timecode. i.e. filename-start-time_end-time.mov The % variables don’t seem to be well defined in the documentation. I have it working with strtime 1 and using %H%M%S type variables. Is there a reference for the %variables ?

Re: [FFmpeg-user] Question on Segment TImes
The tape deck is a Sony DSR-45 (not the “A” model). The tapes are pre-recorded studio dubbing masters. When I do ffprobe with avfoundation it produces this output: Stream #0:0: Video: dvvideo, yuv411p, 720x480 [SAR 8:9 DAR 4:3], 25000 kb/s, 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc Stream #0:1: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s Stream #0:2: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s I was unable to map anything resemble 0:1 or 0:a:0 coming in from the deck. Once it was in an DV file, it worked as expected. I had not thought of this before, but perhaps I can map 0:v:1 to audio? Maybe it sees it all as a video.

Re: [FFmpeg-user] Question on Segment TImes
Is there a way to consolidate this to one command?
The goal is to import of DV-TAPE with the best quality in a single pass on the
tape. Sometimes I have go back and parts from FCPX imports. The tapes are old
and sometimes FCPX doesn’t like them.
I was able to get it going with a PIPE: (and 30 experiments on time coding and
segment timing)
export TITLE="284_test"; \
ffmpeg -benchmark_all -stats -loglevel debug \
-c dvvideo -pix_fmt 0rgb -capture_raw_data true -f avfoundation -i DV-VCR \
-c: copy -f dv pipe: | ffmpeg -i pipe: -c:v dvvideo -c:a:0 pcm_s16le \
-strftime 1 \
-copyts \
-timecode "00:00:00;00" \
-increment_tc 1 \
-reset_timestamps 1 \
-segment_time 00:05:00 -f segment "${TITLE}_%H-%M-%S.mov" -y
This yields the following:
bash-3.2$ ffprobe -show_streams -select_streams a 284_test_004_18-00-51.mov

Re: [FFmpeg-user] Question on Segment TImes
OK: That solved the timestamp problem and created a missing stream. Does anyone one know the magic option for getting all three streams into MOV. If I use this to create a DV file (from DVR-DV) it works and creates this file: ffmpeg -capture_raw_data true -f avfoundation -i DV-VCR -map 0 \ -map_metadata 0 \ -c:v copy \ -c:a copy \ -c copy \ -t 10 output.dv -y Input #0, dv, from ‘output.dv’: Metadata: timecode : 00:00:00:00 Duration: 00:00:10.01, start: 0.00, bitrate: 28771 kb/s Stream #0:0: Video: dvvideo, yuv411p, 720x480 [SAR 8:9 DAR 4:3], 25000 kb/s, 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc Stream #0:1: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s Stream #0:2: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s Three streams If I just change the container to “.mov” ffmpeg -capture_raw_data true -f avfoundation -i DV-VCR -map 0 \ -map_metadata 0 \ -c:v copy \ -c:a copy \ -c copy \ -t 10 output.mov -y I get one stream: nput #0, mov,mp4,m4a,3gp,3g2,mj2, from ‘output.mov’: Metadata: major_brand : qt minor_version : 512 compatible_brands: qt encoder : Lavf58.35.101 Duration: 00:00:10.01, start: 0.00, bitrate: 28773 kb/s Stream #0:0: Video: dvvideo (dvc / 0x20637664), yuv411p, 720x480 [SAR 8:9 DAR 4:3], 28771 kb/s, 29.97 fps, 29.97 tbr, 1000k tbn, 29.97 tbc (default) Metadata: handler_name : VideoHandler I have tried every variation of -map. If I send the output to pipe and then to a file, all of the streams are their for DV If I do the import with Final Cut Pro X then I get this from the file.

But you can use pipe output and cut the file, that should unproblematic with dv files.

Re: [FFmpeg-user] Question on AVFoundation and importing from a DV-VCR
Thilo, Good Morning I am using the Mac ports ffmpeg-devel version. I can compile it from scratch for testing. The reason for trying to keep the original time stamps (which does not seem to happen) is I wanted Final Cut Pro to have the original scene information for splitting. The tapes are from a video studio I acquired and I am going to remaster them for re-release. So I need the maximum quality from the take. I think the issue is related to ffmpeg taking a set of defaults based on the first stream detected and then there are multiple streams (at least 3 or 4) which require defaults to change. My idea was to import the video raw to a file and then have FPCX do the import on the file. FCPX does not seem to work the same on a file as it does on controlling the deck for import. I am trying to streamline a workflow because after I finish 500 DV tapes I have another 500 8MM tapes to go.

However, your build is too old to have the latest patches to avfoundation. Which are especially important for you because I fixed the end of recording bug. There is no release yet featuring it, get a build from after March 5th. -Thilo ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe". ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

And also does FCPX seem to lose control over the deck for no reason at all sometimes? I had a hell of a time and ended up using boot camp and premier pro as a workaround, macOS Catalina doesn't seem to like dv at all and hates HDV only marginally less. Yeah, that’s about right. I have adobe premiere but they cut all support for DV in the Catalina. I contact support about it. Scene detection for splitting doesn’t seem too appealing, try if more direct access to the deck gives you more options with libdc1394. (personally I would either downgrade to mojave and use final cut there, or install windows 10 and premier with their trial/nfr licenses and archive all the dv tapes you have now. Even on mojave the newer versions of FCPX are finicky with tape decks :/) I turned off all of the processing during ingestion. Seems to be a bit better. I just can’t sit an wait for the last frame to stop the import.

[FFmpeg-user] Question on AVFoundation and importing from a DV-VCR
To Whom It May Concern: I have been trying to get a direct import from a Sony DSR-45 DV Deck. Using OS X Final Cut Pro hot annoying with various issues. Does anyone have suggestions or a method for doing this better? I have 500-600 more DV tapes to ingest. Using this command brings in a 12GB DVVIDEO files ffmpeg -hwaccel videotoolbox -hide_banner -benchmark_all -stats -loglevel error -f avfoundation -capture_raw_data true -pix_fmt 0rgb -i DV-VCR -t 600 -q 0 -c:v copy -c:a copy 'Test7.dv' -y The problem are: 1. The file is huge (Is there a way to auto split this with a scene detect filter? I have not tried this yet. 2 The videos I am working with consist of: a. Intro video track no audio b. 60 second intro (apparently with different time codes) c. A 45 minute to 60 minute video What I get is either the intro video is too slow or the actual video I want is too fast. It seems to depend on whether I start the tape before the intro text, or during a video. I am guessing different time codes. I tried a number of test cases results varied but in all cases one or the other video was bad. My next round of testing will be with " -capture_raw_data false" Test Cases: ffmpeg -hide_banner -benchmark_all -stats -loglevel error -f avfoundation -capture_raw_data true -pix_fmt 0rgb -i DV-VCR -t 140 -copyts -copytb 0 -vsync passthrough -c:v copy -c:a copy 'Test 1.dv' ffmpeg -hide_banner -benchmark_all -stats -loglevel error -f avfoundation -capture_raw_data true -pix_fmt 0rgb -i DV-VCR -t 140 -c:v copy -c:a copy ‘Test 3.dv' -y I am running this on a MacBook Pro (10.15 Catalina) ffmpeg version 4.2.git Copyright (c) 2000-2020 the FFmpeg developers built with Apple clang version 11.0.0 (clang-1100.0.33.17) configuration: --prefix=/opt/local --enable-swscale --enable-avfilter --enable-avresample --enable-libmp3lame --enable-libvorbis --enable-libopus --enable-librsvg --enable-libtheora --enable-libopenjpeg --enable-libmodplug --enable-libvpx --enable-libsoxr --enable-libspeex --enable-libass --enable-libbluray --enable-lzma --enable-gnutls --enable-fontconfig --enable-libfreetype --enable-libfribidi --disable-libopencore-amrnb --disable-libopencore-amrwb --disable-libxcb --disable-libxcb-shm --disable-libxcb-xfixes --enable-opencl --disable-outdev=xv --enable-audiotoolbox --enable-videotoolbox --enable-sdl2 --disable-securetransport --mandir=/opt/local/share/man --enable-shared --enable-pthreads --cc=/usr/bin/clang --arch=x86_64 --enable-x86asm --enable-libx265 --enable-libdc1394 --enable-librtmp --enable-gpl --enable-postproc --enable-libx264 --enable-libxvid --enable-version3 --enable-libsmbclient --enable-nonfree --enable-libfdk-aac ====== Colin Bitterfield co...@bitterfield.com https://www.linkedin.com/in/colin-bitterfield-80612327/ == ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
