I posted this question 2+ years ago and it has nearly 58,000 views and we still don't have a consensus that it's a legitimate problem, let alone a solution from Adobe that does not involve getting third party applications involved. I would like to point out, despite some opinions to the contrary, that Sony Vegas is a "professional" application and it supports variable frame rates without issue. Still.

If anyone from the staff group is actually paying attention, you should pay attention to how those of us with thousands of dollars invested in your product are being treated on the official support site.

Fair enough, but argument there would be that while Xsplit is $30, Premiere Pro is...much more. Also, this program is not the only that records in variable frame rate, sometimes by necessity. I mentioned above that recent iPhones will often dip into variable frame rates in low light. And if a user can't know for sure if its variable or static, I just think software should make good faith efforts to plan for it. Obviously Sony's Vegas has done so. I'm not saying something couldn't be done on both ends.

I have tried that. I can 'massage' the out of sync issues a bit but it still goes one way or the other. Mapping a variable frame rate to a static one just continues to cause problems.

Xsplit seems to be a self contained "live broadcaster" of media compiled within it self. THen it streams to various "web broadcasters". Asumeably it keeps (records) a copy of what it is streaming? What do you need Premiere for? Just curious about this. After the live broadcast we take the recorded file and edit it for time and offer it on demand.

If the editing of these file is so important in your studio environment and business..why would you not train your people in an application that fully meets your needs. eg Vegas if thats the case as you say it does 100%. They are only tools....and choosing the right one for the job would be seemingly logical and productive. Maybe down the track ...Premiere will be able to do what you want. Both the major programs for game streaming and live stream, Xsplit and Wirecast, record files that are variable frame rates. Both have the same problem as we have tried both applications. The reason we are using Adobe still is that we have been using PP for many years BEFORE doing live streaming was part of our portfolio. We still do other video projects including commercials using DSLRs for video and I'd rather not have to move away from what we have invested (in time and software) on Adobe.

Well, if Apple's own Quicktime can't make the file work, I don't think Adobe can do anything to fix what is, after all, an Apple product Actually the files we are trying to edit come from Xsplit, not anything Apple.

Currently I know 100% that Sony Vegas will handle real time editing of these files without issues but our people are simply not trained on it and I have invested quite a bit in the Adobe ecosystem as it stands. We have used conversion apps in the past yes and it can SOMETIMES fix it by stabilizing the frame rate but other times the problem remains - this happened to be one of those days. Also, that can add 30-50 minutes of transcode time per file to the workflow which can be damning in the world of real-time video.

While I appreciate your replies, you aren't helping at all. We use a mix of harware in our studio including consumer level camcorders, higher end devices like the 7D and 5D Mark II and sometimes we record live events as well. Telling a customer to "use better hardware you unprofessional loser" is about as professional as you seem to think I am. I am looking for solutions, and actual answers as to why Adobe continues to NOT support this kind of workflow while their competition DOES.

Maybe, but I cannot tell you how much I LOATHE this answer I see all the time from people on this and other professional boards. I am in a "professional production environment" and we are using "professional" software. I realize it's not 'normal' but keep in mind that the iPhone, the most popular camera in the US today, records video at a variable frame rate and that Premiere Pro, one of the most popular pieces of software still can't properly handle it and keep in sync. I don't understand how software like VLC and WMP can playback the file just fine but the minds at Adobe can't figure out a way for us to this video in our projects. It just boggles my mind. There has to be an answer!

The file I am trying to edit was recorded in a streaming application called XSplit, very popular in the game / live streaming community. The frame rate is variable, slightly I am guessing, because the real time nature of the recording/stream. The issue is that while WMP and VLC play the file back 100% correctly, when played back inside Premiere CS6 the file drifts out of sync so at the end of a 2 hour clip, we are talking more than a full second or so. According to MediaInfo, here is the file detail: General Complete name : Y:\Live\2012-12-4 Farcry 3\2012-12-04_200413079.mp4 Format : MPEG-4 Format profile : Base Media Codec ID : isom File size : 4.33 GiB Duration : 2h 11mn Overall bit rate : 4 713 Kbps Writing application : Lavf54.0.100 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : High@L3.1 Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 2h 11mn Bit rate : 4 574 Kbps Width : 1 280 pixels Height : 720 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Frame rate : 29.970 fps Minimum frame rate : 5.000 fps Maximum frame rate : 30.303 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.166 Stream size : 4.20 GiB (97%) Writing library : x264 core 125 r2200 999b753 Encoding settings : cabac=1 / ref=1 / deblock=1:0:0 / analyse=0x3:0x113 / me=hex / subme=2 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=0 / me_range=16 / chroma_me=1 / trellis=0 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=0 / threads=18 / lookahead_threads=3 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=1 / b_bias=0 / direct=1 / weightb=1 / open_gop=0 / weightp=1 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=10 / rc=crf / mbtree=1 / crf=13.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / vbv_maxrate=5000 / vbv_bufsize=7000 / crf_max=0.0 / nal_hrd=none / ip_ratio=1.40 / aq=1:1.00 Audio ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : 40 Duration : 2h 11mn Bit rate mode : Constant Bit rate : 128 Kbps Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 44.1 KHz Compression mode : Lossy Stream size : 120 MiB (3%)

Variable frame rate video comes from many places these days: phones, live streamed video recordings. Adobe Premiere is a supposedly production level piece of software that cost a good chunk of change. How is it 2012 and Adobe does not still have an answer to this problem? After trying to editing/convert/mux/edit variable frame rate videos for the past 5 hours I am just exhausted. No amount of conversion apps, etc have saved us and THEY SHOULD NOT HAVE TOO. We have spent thousands on Adobe software packages over the last decade, probably 10s of thousands, and the only answer I find consistently is to switch to Vegas. Surely, SURELY someone at Adobe with real insight into the issue can help answer the question of whether users moving into different medium should find a place elsewhere in the software ecosystem...

I am trying to record files to the FM server as we stream them as a back up to our local recordings via Wirecast. The process is working, but we have to change the name of the stream in Wirecast, and thus the stream name in our video embed code, EVERY TIME we stream, otherwise the file simply gets overwritten. I am trying to find a way to add something like a date/time code to the beginning of the file name that is recorded so we won't have to worry about that anymore. Here is the code as it was given to us currently: application.onPublish = function( client, stream ) { if( (client.agent).indexOf("Wirecast/FM") == -1 ) return; //Make dvr info object var info = new Object(); info.streamName = "mp4:"+stream.name; info.callTime = new Date(); info.startRec = info.callTime; info.stopRec = new Date( 2099, 11, 31, 17, 59, 59 ); info.maxLen = 0; info.begOffset = 0; info.endOffset = 0; info.append = false; info.offline = false; info.dynamicStreamSet = info.streamName; //Call set DVR info client.DVRSetStreamInfo(info); } I can't find any documentation on what "dynamicStreamSet" is. If I change "info.streamName" then nothing records, but if I change "info.dynamicStreamSet" the file name is still "stream.name" rather than what I have changed it to. Any ideas or help? Thanks!!
