Hi, When rendering files with the h264 codec, does it matter whether they are Quicktime files (mov extension) or mp4 files (mp4 extension)? Will Watchout use its native multithreaded decoding methods in either case, or will this only be done if the extension is mp4? thanks
Good afternoon. I apologize in advance for probably a stupid question, but 1) What is the best codec settings can be recommended for video playback vachout on the LED display resolution of 8448 * 1080 pixels. 2) What are the possible ways to improve the performance of "computer display" Currently this causes considerable difficulties. We have to share the source video into two parts at ~ 4k. In addition, playback of multiple layers of system dumps into a tailspin. I would be glad of any possible assistance. Thank you in advance.
Hi there, we are shooting a tv series in switzerland and want to feed our Insight 4k quad from digital projection with footage which is in ProRes 422 10 Bit UHD (4k) with 50 fps. We use the rear projection method instead of greenscrean to get real reflections in the surfaces that are infant of the projection.. So we already tried out a media server from 7th sense, but i was very unhappy with workflow, so now i want to try out whatchout an i am wondering if i could get realtime playback with good performance with our editing workstation, here are the specs: HP Z640 Workstation, CPU E5-2643 v3 3.40 GHz (2 Processor), 64.0 GB RAM, NVIDIA GeForce GTX Titan X (12GB RAM), Windows 10 first question is, do you think this setup could work for 4k 50fps? Any codec suggestions(i heard pro res would´t be good for playback, maybe .tga? We want to have it as uncompressed as possible since we film from that projection and don't want to get weird artefacts.. Second question: We have Ambient Timecode which is able to give out genlock signal, so now i´m thinking about to get a new graphics card since the gtx doesn't support genlock via bnc input.. Third question: I think i would need a fast drive solution for the media, any suggestion on that? internally ssd RAID? I would be very happy for every helpful comment, i´m new here by the way thanks Stephan
Hello, I work for a video company in Argentina. We have WO 5.1. We recently did a mapping projection with 13 displays. We used 7 Display computers (2 outputs each) and a production computer. We projected 3 walls of an event conference room. The main project size was 12595px X 553px. We splited that main video in 7 parts according to the diferent blendings and wall sizes. At the same time, the main video lenght was 40 minutes separated in 8 five minutes parts. The 7 videos sizes were: 2 videos of 2662x417 splited in 2 parts of 1331x417 each. 3 videos of 1843x553. The codec (converted with Procoder 3) used was: - Mpeg2: .m2v - 25 fps - interlacing = lower field first - bitrate = 24.000 Audio: - 2 separate audio tracks WAV (16 bit, 44.100) Production computer and display computers: - Intel Core i7 3.07gHz - ram = 2gb - win 7 32 bit - Ati radeon HD 5670 - Windows 7 32 Bit Here is the issue. Each time we loaded a video in the timeline, the response speed of Watchout slowed a bit. When we completed loading all the videos in the WO project, everything became SO slow. I mean, when we press play, the video runs perfectly in all the displays but when we press the space bar to pause the playback it takes about 15 secs (or more) for the video to stop. If we wanted to move the cues of the timeline it also worked extremely slow. We rebooted all the computers, and reopened the project with same results. During the essays we pressed play and the video playback was ok until minute 35 (of 40) when the displays started to loose a bit of synchronization. To avoid this we inserted a pause and play cue in the middle of the video and that worked to avoid desynchronization. Yesterday i tried to do all the project again and tested performance. When i loaded about 4 videos of this kind in the timeline, i saw a bit of latency in the production computer to pause playback, resize cues, scroll the timeline, etc. I hope you can understand me (my English is not the best). If anyone see what things we are doing wrong or what could be our problem please answer this topic. Thanks in advance. Julián.
