Re: Conform 25fps to 24 or 23.976fps - 8 years ago
Was the footage shot at 25 fps? If it was shot at 24 fps and you made an error in creating the 25 fps .mov file from it, it probably has a doubled frame every second. Play that 25 fps .mov file in QuickTime and advance frame-by-frame. Are there doubled frames? If the 25 fps .mov file really has 25 different frames per second then you can conform it using Cinema Tools or QT Edit to 24 fps.by dcouzin - Café LA
Re: Question about drives and transfer rates? - 8 years ago
Disk transfer rates probably don't figure into rendering. In rendering, the video is read from disk decoded effects-processed encoded written to disk For red-band (necessary) rendering, the real time engine couldn't keep up with 1-3. I think the operating system is smart enough that processes 1-3 go on simultaneously (a tad out of synch) in real time playback, so whichever process is thby dcouzin - Café LA
Re: dropped frames in Cambodia - 8 years ago
Ben's and Derek's warnings about overly full hard drives should be taken very seriously. My use of "old wives' tale" was over-the-top (as well as sexist) but it is really hard to stimulate investigation in this forum. I just did a little speed experiment. I copied a 23.92 GB folder from a RAID 0 drive over and over to a simple eSATA drive. The eSATA drive had capacity 249.72 GB,by dcouzin - Café LA
Re: dropped frames in Cambodia - 8 years ago
It's one big old wives' tale. Both the data loss tale and the dramatic speed loss tale (due to overly full HDDs) pertain to system disks, not to defragged/compacted scratch disks. Ben's post in a recent strand included a videoed explanation of how read speed decreases with HDD filling. See the graph at minute 1:17 of the video. Read speed decreases gradually from empty to full, progressing liby dcouzin - Café LA
Re: dropped frames in Cambodia - 8 years ago
QuoteBen King...and no more than 80% full for safely storing data - any fuller and you run the risk of data loss. I suspect that defragmentation/compaction lets you fill big HDD volumes with video data to even more than 90% with full safety. After all, it's not a system volume that's creating various caches. I use iDefrag often to defrag/compact and it has never messed up. Dennis Couzinby dcouzin - Café LA
Re: removing bad FCP "pulldown" - 8 years ago
By "29.97 sequence" you seem to mean a 29.97p sequence, since you speak of "editing out the frames". If FCP doubled the first frame of each group of four frames this is not "bad FCP pulldown". It is an expected "nearest frame" rate conversion for 24->30. Then it is possible to do a "nearest frame" rate conversion from 30->24 to eliminateby dcouzin - Café LA
Re: Video in canvas plays darker, playhead stops image lightens* - 9 years ago
Shane, as I've explained before, the calibration of the computer monitor must take into account the idiosyncracies of the "player", in this case FCP7, the OS, and the graphics card. My method of calibration involves putting a test clip into FCP7 and measuring the colors on the canvas. When the various Y'CbCr in the test clip yield correct colors on the canvas calibration is complete.by dcouzin - Café LA
Re: Problems installing FCP - 9 years ago
"...retaining the files recommended if you intend to re-install" sounds like your false step. You're not re-installing FCP6 (FCS2), but trying to fresh-install FCP7 (FCS3). Dennis Couzin Berlin, Germanyby dcouzin - Café LA

Re: Photo Montage SD DVD - 9 years ago
Simply make the SD DVD 16:9. HD implies 16:9 but SD does not imply 4:3. Notice that 720:480 is not equal to 4:3. Making the pixels in the 720:480 a little higher than wide can give 4:3 image proportions. Making them a little wider than high can give 16:9 image proportions. SD 720x480 is flexible about this. FCP Sequence Settings call this "pixel aspect ratio". For 720x480 videoby dcouzin - Café LA

Re: Converting Canon C300 footage shot at 30fps, 48fps, and 60fps to play at 23.98fps in Final Cut 7 - 9 years ago
Your camera shot at 60 fps and made a 24 fps clip from this so it's 60/24 =2.5× slomo in your 24 fps sequence. To make it natural speed again you just need to discard 36/60 = 3/5 of its frames. Trouble is, you can't drop 3/5 of the frames in a perfectly regular way. You will wind up doing something like converting ABCDEFGHIJK... to ADFI... where the time between A and D in the world was 3/60by dcouzin - Café LA
Re: Question about drives and transfer rates? - 9 years ago
Ben, the problem is precisely that you did write:These are all theoretical maximums but error correction and other overheads take their toll and you never see perfect sustained full speed. Yet for SATA you included the hefty 8b/10b error correction factor in your calculation, while for FireWire 800 you did not include the same 8b/10b error correction factor.

Re: Question about drives and transfer rates? - 9 years ago
I appreciate Ben's discussion of the big storage question. His linked explanation of the slowed read/write of more full drives is important, and perfectly analogous to the phonograph record. His reminder that RAID is not backup is also important. RAID 0 (which really shouldn't be called RAID, because there's no Redundancy) is the fastest simplest RAID variant. Since I routinely backup, anby dcouzin - Café LA
Re: Question about drives and transfer rates? - 9 years ago
You can't ask that question without specifying the codec, resolution, and frame rate. Also the number of simultaneous streams. And also the processing power of the computer. Some idea of hard drive requirements can be gotten from page 16 of the Apple ProRes White Paper of July 2009 (not the October 2012 White Paper). Crudely estimate the three-drive RAID 5 read speed as twice the single driby dcouzin - Café LA
Re: Question about drives and transfer rates? - 9 years ago
It's analogous to phonograph records. The rpm does not indicate the high frequency fidelity. Indeed the progression from 78 rpm to 33 rpm phonograph records yielded higher fidelity in spite of the rpms, because the grooving and the cartridges became much more precise. Also not all records, and not all cartridges, provided equal fidelity at the same 33 rpm. For a given rpm, HDD data read spby dcouzin - Café LA
Re: fcp 6 autosave questions - 9 years ago
BabaG: What you did is reasonable, and FCP7 does it fine. It doesn't seem possible that FCP6 can't do it, since every new project starts as a "save project as". (You're not running FCP6 under Mavericks, are you?) You can try opening a new project, copying one of the partial projects' contents into it, and saving that new new one. Also are you sure you edited long enough to get an autby dcouzin - Café LA
Re: Best codec for H.264 camera footage - 9 years ago
Quotedcouzin I haven't seen the problem because I never edit in H.264 in FCP7. Who would, after reading in this forum about its problems? I finally dared to edit a little piece in 1920x1080 50i H.264 (clips straight from an AVCHD unwrapped by ClipWrap). After three hours, the edit disappeared without warning just as Derek warned.

Re: the unnecessary deinterlace bug - 9 years ago
Touché. Maybe. Are you certain that "a proper reference monitoring system" will be immune to FCP7's bug? The reference monitoring system is not monitoring a file, but rather the contents of the FCP7 timeline. If for certain codecs FCP7 sends poop from the timeline to the 100% canvas (but not to the export), then how do we know what FCP7 sends to the reference monitoring system?by dcouzin - Café LA

Re: The cost of editing is becoming perpetual. - 9 years ago
There are multiple issues here: ownership, continuity, and flexibility. Editors are craftsmen, and softwares are their tools. A craftsman owns his tools so he can use them as little or as much as he pleases and for as long as he pleases and also so he can customize them to fit his special needs. Editing software is complex enough that it probably should be written professionally, even by greby dcouzin - Café LA

Re: Final Cut 7 on new Mac Pro -- can't read C300 files - 9 years ago
Shane Ross suggested a Canon plugin here, but that was in 2011. Will the plugin run under Mavericks? The title "on a new Mac Pro" should be understood as "under Mavericks". The new Mac Pro compels Mavericks. I'm so very happy I bought a 2012 Mac Pro (in order to run OSX 10.6.8) instead of the new one. Dennis Couzin Berlin, Germanyby dcouzin - Café LA
Re: NTSC to 24fps - 9 years ago
Nick: it's actually disturbing when composited TV looks perfect. VHS, especially, should look imperfect. If it doesn't have to look accurately imperfect just use Compressor with some bad settings.

Re: NTSC to 24fps - 9 years ago
Conforming it to 30 fps changes it from 59.94i to 60i but does nothing for the underlying problem: how to make 2 frames depicting 2 moments from 5 fields semi-depicting 5 moments? I suggest changing 60i to 24p in two steps. First change the 60i to 60p by "double interlacing". You can find software to do this or else use the DIY method here. Second change the 60p to 24p.
