MP4 videos (both homemade and purchased) are jumpy and voice/video not synced
It's not strange at all that some will work and others will not unless every video uses the exact same codec, is the exact same resolution, the exact same bitrate, etc. More than likely (re 99% certain) you are using an assortment of videos from 360p (easiest to play) up to 1080p or 4k, using a variety of bitrates. I see it all the time. With your current laptop you would need to stick with 480p 1,000 kbps videos that use the H.264 (or x.264) codec to stand a chance of playing back well. Think of it like this. Some videos weigh 2 or 3 pounds and even a youngster can pick them up and carry them around. Some videos weigh 100 or more lbs and you need to be an adult and fit to move them easily. The higher the bitrate, resolution, codec, etc. the more the video weighs.
And yes, you need to stick with releases of EW 7 that start with 7.1. NONE of the 7.2 releases will work well with EITHER of those laptops as neither comes close to meeting the recommended specs to run EW. The Acer with the low end Nvidia 940MX meets the MINIMUM specs and would probably handle 720p resolution video projected to a SINGLE screen (as in NO FOLDBACK) as long as you stick with videos (or motion backgrounds) that are 720p or less and low bitrate. I wouldn't run a 7.2 release on it tho.
Got it. So, bottom line is we need to invest in a new worship laptop that meets the recommended specs for EW. We've been considering replacing our current laptop for a while due to its age, but now we know what we need to be looking for specifically if we want to be able to use EW (and all it's future updates) moving forward.
SO appreciate your time and expertise.
Here's a link to the EW Specs page.
Lately we are having issues playing MP4 videos that we have imported into EZ worship. Some work just fine while others are terribly jumpy and the sound & video are not in sync. Can't seem to figure out why some work and some don't. Help!!
