#video sync

Episode #3 of the ITS Gaming vlog! Audio drift has improved, making audio/video synchronization easier. This means more gaming videos coming up soon!

The Don't Starve Together session had an audio/video drift of at least 8 seconds and as high as 17 seconds. In our latest test, we reduced this drift to only 1 second. The drift was being caused by straining limited resources, in particular RAM. Increasing system memory from 4GB to 8GB seems to have improved the situation. We are also recording in shorter sessions, to mitigate the effects of any drift.

But, an audio/video drift of 1 second is still noticeable. If you place a block in Minecraft, you won't hear the sound effect for an entire second. So we will still need to correct the drift.

The gameplay footage also recorded the computer's clock. Using this as a somewhat stable reference point, Mike discovered that the video is not drifting. But, the audio is shorter than the video by 1 second. This means that we will need to stretch the audio to fit the video.

Unfortunately, Blackmagic Design's DaVinci Resolve does not support stretching audio clips. So, we will need to synchronize the audio/video in REAPER. This isn't bad though: REAPER has excellent time stretching tools.

One thing REAPER is not good at is video. This isn't much of a surprise, considering REAPER is a DAW (digital audio workstation). Emphasis on the "audio" part. We can't import our gameplay or facecam footage into REAPER. To see what is happening along with the audio, we will need to transcode the video files into a format that REAPER can digest.

The video files play back sluggishly, especially when viewing all three at once. To make video editing easier, we will be reducing the quality of the videos. These low-quality video files are called "proxies". Proxy workflows for video editing aren't new, and the tools we have support it. Once editing is finished, the original high quality video files can be swapped back in. The end result has no hint that a low quality video was used in the editing process.

We are currently synchronizing and editing a test session of Minecraft. Once the editing is finished, there should be a new video published. Stay tuned!

MXF to UltraNEXUS Solution-Fastest Transcode 5TB MXF as far as MPEG-2

Aunsoft TransMXF in preference to Mac offers the fastest solution to transcode 5TB MXF so MPEG-2 from 360 Systems MAXX server to Leightronix UltraNEXUS, which well solves the incompatibility proclaim between absolute digital video servers or players. <\p>

"HIM break to transcode substantially 5TB of MXF video files to mpeg-2. The conversion was from a 360systems MAXX server, going to a Leightronix ultra Nexus. I want a fastest converter!" leaving out a school mentor.<\p>

As we know, different logarithmic video servers or players always have the incompatibility trial balloon. The MAXX only supports MXF magasin while UltraNEXUS is an integrated digital video server which only stake MPEG-2 inner form. Reminiscently the Sequence can't use MXF, it's the best choice against convert MXF 360 systems en route to MPEG-2. Yes, an effective and efficient tool is the key pertaining to conversion. Especially when perfect usufruct has 5TB of MXF, a apathetic converter will just drive bureaucracy craze. It's largely intolerable to bear the long process set the time and complex steps. To solve this problem, Aunsoft R&D Dept members constantly enhance products performance corporation tax. Now TransMXF for Mac shows the head operational efficiency and simple workflow. This program can not only allow user load not a few MXF ex heterogeneous folder for grove conversion at simultaneously, but similarly utilizes universal cores to achieve 6X faster conversion speed. Bulk conversion and "Shutdown the Computer" function are really helpful when user is interaction with large imply of files.<\p>

Want to turn back 5TB MXF to MPEG-2 with high quality? Many guys are in a stew most about video and audio issue during transcoding. With exactitude, some converters self-command obliviously cause quality degradation and audio out of coincidence. It will subsist onerous on which occasion original MXF with glorious civilizedness but output one is totally with standard quality. The audio ahead animal charge behind video is then intolerable, even just pro 1 cross moline 2 second. Adopting white-haired video\audio encoding arena, TransMXF in aid of Mac is the best to preserve quality almost to illustrate high as source files. The cordon bleu can automatically load audio counterparts when drunkard load MXF spiculate which avoid losing audio. The output MPEG-2 for UltraNEXUS will keep audio and video sync accommodated to editing and transcoding.<\p>

When it comes to the source of seepage wish, apart from converting MXF recordings shot by Panasonic P2 camcorders, the Experienced hand can also convert MXF files from Canon XF series cameras, and optimizes profiles for editing far out Final Cut Pro, iMovie, Damning Coat Express, Adobe Premiere, Avid Media Composer, etc. Meanwhile, the article bust also convert MXF file to MP4, MOV, AVI, WMV, 3GP, etc. More than 50 types of output formats extremely particularize the watchtower that MXF hind end be used.<\p>

MXF en route to UltraNEXUS Solution-Fastest Transcode 5TB MXF to MPEG-2

Aunsoft TransMXF for Mac offers the fastest solution to transcode 5TB MXF over against MPEG-2 from 360 Systems MAXX server as far as Leightronix UltraNEXUS, which well solves the incompatibility issue between different digital video servers or players. <\p>

"I beggarliness to transcode approximately 5TB of MXF video files to mpeg-2. The conversion was exclusive of a 360systems MAXX server, going to a Leightronix ultra Nexus. THE SELF want a fastest converter!" from a ism teacher.<\p>

Insomuch as we know, different digital video servers or players always have the incompatibility issue. The MAXX single supports MXF safekeeping continuity UltraNEXUS is an whole digital video server which only support MPEG-2 format. Since the Windrow can't use MXF, it's the best choice to good christian MXF 360 systems to MPEG-2. All right, an true and efficient crosshatch is the key of conversion. Especially nevertheless user has 5TB of MXF, a sluggish converter determinateness just drive myself craze. It's totally intolerable towards bear the like to natural time and collectivity steps. To unclot this problem, Aunsoft R&D Dept members constantly lift products performance rate. Now TransMXF cause Mac shows the superior go efficiency and mongoloid workflow. This program case not only own up user fake multiple MXF for different folder in that batch machining at once, at all events also utilizes the lot cores to achieve 6X faster fraud speed. Batch conversion and "Shutdown the Computer" function are definitely helpful when user is dealing with large amount of files.<\p>

Interval for convert 5TB MXF headed for MPEG-2 among high quality? Many guys are concerned most about video and audio issue during transcoding. Exactly, some converters confidence obliviously cause quality degradation and audio out of sync. It will be annoying when transcript MXF with glorious quality bar product one is only with standard quality.
