Work out your average source length before you compare anything else
Vizard states its meter plainly on the pricing page: 1 credit equals 1 minute of video, and every minute you upload costs a credit. Creator and Business both start at 600 credits a month, with larger annual credit packs available on the same tiers. ClipForge counts projects instead, at 20 a month on Creator with sources up to 2 hours, and 100 a month on Pro with sources up to 4 hours.
Divide one by the other and the crossover is exact. 600 Vizard credits against 20 ClipForge projects means the two plans buy the same throughput when your average source runs 30 minutes. Publish forty 8-minute videos a month and Vizard covers it inside 320 credits while ClipForge Creator ran out of projects at twenty. Publish twelve 75-minute interviews and ClipForge has used 12 of 20 projects while Vizard needs 900 credits against an allowance of 600.
This is worth doing on your own numbers before reading another feature table, because it is the largest single cost difference between the two products and it is decided entirely by the shape of your content library. Look at your last ten uploads, total the runtime, divide by ten. If the answer is under 30 minutes, Vizard is likely cheaper for you and this page is telling you to buy it.
