14 Plugin GUIs improved
by Phyllis Smith 21 Dec '21

21 Dec '21

Today's checkin includes 14 plugins with improved GUIs to add Tumbler Boxes with current value now visible and ability to type in a specific desired value. Modified plugins are: - alpha + Reset button was added - brightness - huesaturation - linearBlur - polar - radialblur - rgbshift - sharpen - unsharp + hard to use Dial switched to the more consistent slider bar - wave - whirl - yuv - yuvshift - zoomblur Thanks to the Anonymous Contributor for this useful, more consistent, and desirable presentation for these plugins. This was very tedious work.

Is SD and HD 422 Video Capture obtainable with V4L(2)?
by Terje J. Hanssen 19 Dec '21

With reference to Adam Wilt: https://www.adamwilt.com/DV-FAQ-editing.html#transcoding > I-frame-only MPEG-2 is said to be comparable to DV format compression > at the same bit rate. Thus 25 megabit MPEG-2 should yield results (and > transcoding errors) similar to DV, and 50 Megabit MPEG-2 should be > comparable to DV50. > > MPEG-2 at 25 Megabits should be roughly comparable to DV, though its > 4:2:2 color sampling may be more beneficial for graphics. Are 25 Mbps > MPEG-2's benefits worth the transcoding hit coming from DV? It's > arguable: I've been comparing DV25 and MPEG-2 25Mbit, and can't say I > see a huge difference one way or the other. Both have their artifacts, > and their tradeoffs. > > DV50 or MPEG-2 at 50 Megabits will be clearly superior in quality to > DV, albeit at twice the data rate (think about the disk space and disk > speed necessary). Indeed, if you're originating on DV50 (D-9, > DVCPRO50) there's no reason to go with anything other than a DV50 NLE, > using SDTI in place of 1394 for the transfer. The only way up from > DV50, practically speaking, is to to go totally uncompressed -- and > nowadays, that's increasingly viable, what with fast disks and > inexpensive arrays. ==================== As I already pointed on in another thread, a solution to capture Hi8 to SD DV50 in 4:2:2 format was possible already 10 years ago https://lists.cinelerra-gg.org/pipermail/cin/2021-December/004308.html In a more recent thread here, Andrew mentioned a hdmi capture card (with v4l2) https://www.mail-archive.com/[email protected]/msg02865.html =================== Therefore I wonder if we, CinGG users and devs, are able to setup and test a recommended capture solution (w/card and guide) for SD and HD video in 4:2:2 colorspace, preferably using free drivers and tools like V4L/V4L2 and FFMpeg? https://en.wikipedia.org/wiki/Video4Linux https://www.linuxtv.org/wiki/index.php/V4L_capturing Terje J.

Linux drivers for Kona LHe plus?
by Andrew Randrianasulu 19 Dec '21

19 Dec '21

Hello. I am currently poke code of Cinelerra-gg {0} (fork of Cinelerra-HV {1}). Our software (Linux-only, even if you can try to compile on Windows or FreeBSD) tries to be quite high-end NLE with support for 32-bit floating point data path. On your product page https://www.aja.com/products/kona-lhe-plus I see "Supporting macOS, Windows and Linux, KONA LHe Plus offers cost effective simple connectivity for a range of workflows." yet on your (?) driver page https://github.com/aja-video/ntv2-v4l2 I can't see this specific card listed. Does this mean current (hopefully v4l2) drivers for Linux non-public/proprietary? Please indicate if I can forward your reply to our public mail list (cc-ed), or should I paraphrase it. {0} - https://www.cinelerra-gg.org/ {1} - http://www.heroinewarrior.com/cinelerra.php

19 Dec '21

It seems there is some uncertanity about what users/distributors can do with sdk required for working with their hardware? https://patchwork.ffmpeg.org/project/ffmpeg/patch/201704010120.37843.cehoyo… https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=839941 {this is related to HD capture hw we discuss with Terje} Should someone explicitly mail blackmagic's support about this?

Hit the wall trying to pass variable from one class to another
by Andrew Randrianasulu 17 Dec '21

17 Dec '21

I tried to pass variable into class BD_BatchRenderJob : public BatchRenderJob { public: static int get_udfs_mount(char *udfs, char *mopts, char *mntpt) ; BD_BatchRenderJob(Preferences *preferences, int labeled, int fa rmed); char *create_script(EDL *edl, ArrayList<Indexable *> *idxbls); int tsmuxered; }; from class CreateBD_Thread : public BC_DialogThread { static const int64_t BD_SIZE; static const int BD_STREAMS, BD_WIDTH, BD_HEIGHT; static const double BD_ASPECT_WIDTH, BD_ASPECT_HEIGHT; static const double BD_WIDE_ASPECT_WIDTH, BD_WIDE_ASPECT_HEIGHT ; static const int BD_MAX_BITRATE, BD_CHANNELS, BD_WIDE_CHANNELS; static const double BD_FRAMERATE, BD_SAMPLERATE, BD_KAUDIO_RATE ; static const int BD_INTERLACE_MODE; public: CreateBD_Thread(MWindow *mwindow); ~CreateBD_Thread(); void handle_close_event(int result); BC_Window* new_gui(); int option_presets(); int create_bd_script(const char *path, EDL *edl); int create_bd_jobs(ArrayList<BatchRenderJob*> *jobs, const char *asset_dir); int insert_video_plugin(const char *title, KeyFrame *default_ke yframe); int resize_tracks(); MWindow *mwindow; CreateBD_GUI *gui; char asset_title[BCTEXTLEN]; char tmp_path[BCTEXTLEN]; char use_profile[BCTEXTLEN]; int use_deinterlace, use_inverse_telecine; int use_scale, use_resize_tracks; int use_wide_audio, use_farmed; int use_histogram, use_labeled; int use_standard; int use_tsmuxer; int64_t bd_size; int bd_width; int bd_height; double bd_aspect_width; double bd_aspect_height; double bd_framerate; int bd_samplerate; int bd_max_bitrate; double bd_kaudio_rate; int bd_interlace_mode; int max_w, max_h; BD_BatchRenderJob *batchrender; }; but guess I do something wrong because just calling //batchrender->tsmuxered = use_tsmuxer; form void CreateBD_Thread::handle_close_event(int result) result in crash ( NOT WORKING (as far as this functionality is concerned) patchset attached...

slightly updated bdwrite.C please test if you can
by Andrew Randrianasulu 17 Dec '21

17 Dec '21

I looked into libbluray repo and added few more lines in our bdwrite.C not really hevc/UHD ready.. but hopefully now can deal with lpcm inside m2ts (blu-ray pcm audio from my ffmpeg patch)

old libavconv with David's patches for IGS (BD menu)
by Andrew Randrianasulu 15 Dec '21

15 Dec '21

I was building this revision https://github.com/libav/libav/tree/d6251368772a170987387bdc508433c8fcf54cda on arm/termux it required --disable-asm but othervise worked. I applied 4 patches I fished out of mailbox archive with plain cat | patch - p1 patches attached. procedure seems to be documented in patches themselves: === These changes add support for copying overlay streams. So to extract IGS menu from m2ts file: $ avconv -i source.m2ts -vn -an -sn output.mnu To mux IGS menu with h264 video in ts: $ avconv -i video.264 -i test.mnu -f mpegts out.ts Still todo: update mpegts muxer to set correct PID so output may be compatible to BDAV format.

old script - mkframelist
by Andrew Randrianasulu 15 Dec '21

15 Dec '21

I wonder if this old script still works (should make Cinelerra framelist for dir full of images) and if so - can it be included in 'contrib' folder of source tree (because hunting it via google or reimplementing each time one need to make 'list of images' input file for Cin... a bit counterproductive?) not sure about license - this is just support script, not linked to binary and not requred for main editing operations - but still useful IMO for working with image files generated by some other program
